Image forming apparatus having stabilizing device

Abstract

An image forming apparatus includes: an image forming unit that forms an image on a recording medium; a heating device that heats the image formed at the image forming unit, on the recording medium while recording medium is conveyed; a detecting device that is provided on a downstream side of the heating device in a recording medium conveying direction and detects image density and an image defect of the recording medium; and a stabilizing device that is provided between the detecting device and the heating device and stabilizes physical changes in the recording medium.

1. An image forming apparatus comprising:
 an image forming unit that forms an image on a recording medium; 
 a heating device that heats the image formed at the image forming unit, on the recording medium while recording medium is conveyed; 
 a detecting device that is provided on a downstream side of the heating device in a recording medium conveying direction and detects image density and an image defect of the recording medium; and 
 a stabilizing device that is provided between the detecting device and the heating device and stabilizes physical changes in the recording medium, 
 wherein the stabilizing device is configured by a cooling device that cools the recording medium and a curl correcting device that corrects curl generated in the recording medium, and the curl correcting device is provided on a downstream side of the cooling device, the cooling device having higher cooling effect in an upstream side of the curl correcting device than in a downstream side of the curl correcting device. 
 
     
     
       2. The image forming apparatus of  claim 1 , wherein the detecting device irradiates the image formed on the recording medium with light and receives the light reflected from the image, to detect the image density and image defect of the recording medium. 
     
     
       3. The image forming apparatus of  claim 1 , comprising:
 a first chassis that is provided on one side in a horizontal direction and includes the image forming unit, the image forming unit forming the image on the conveyed recording medium; and 
 a second chassis that is provided on another side in the horizontal direction, the recording medium being conveyed from the first chassis to the second chassis, 
 wherein the heating device, the stabilizing device, and the detecting device are provided in the second chassis. 
 
     
     
       4. An image forming apparatus comprising:
 an image forming unit that forms an image on a recording medium; 
 a heating device that heats the image formed at the image forming unit, on the recording medium while recording medium is conveyed; 
 a detecting device that is provided on a downstream side of the heating device in a recording medium conveying direction and detects image density and an image defect of the recording medium; and 
 a stabilizing device that is provided between the detecting device and the heating device and stabilizes physical changes in the recording medium, 
 wherein the stabilizing device is configured by a cooling device that cools the recording medium and a curl correcting device that corrects curl generated in the recording medium, and the curl correcting device is provided on a downstream side of the cooling device.
